i have them and the work out great. only wish they were black so that they'd match the rest of the motor.
Pony,
Two short sound clips...little loud due to being somewhat enclosed but it gives you an idea of the setup.

I had a gasket blow out with mine. I switched to stage 8 locking header bolts and remflex gaskets and have had 0 issues with mine since. I would do the locking header bolts and remflex gaskets right away so you dont have and issues.
Are you sure it's the gasket and not a loose header bolt? You can remove the starter motor and jack up the engine to get to it.
